One of the first Rock en Español bands in Colombia, Los Aterciopelados is one of the Latin American country's top groups. The recipients of Grammy award nominations in 1997 and 1998, the band has fused its own sound by combining a rock-solid approach with a variety of Latin American musical traditions including mariachi, bolero, tropical and flamenco. Los Aterciopelados, whose name translates as "the Velvety Ones," was formed by former members of Delia Y Los Aminoacidos -- Andrea Echeberry, who plays acoustic guitar and sings lead, and Héctor Buitrago, who plays bass. Original drummer Andres Giraldo was replaced by Alejandro Duque in 1995 and original guitar player Charlie Marquez was replaced by Alejandro Gomez Caceras in 1997. Gozo Poderoso was issued in early 2001.
